SPECIFICATION forming part of Letters Patent No, 652,726, dated June 26, 1900. Application filed-December 30,1899 Serial lie. 742,119. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES W. SHER- BURNE, a citizen of the United States, residing at Boston, in the county of Sutfolk and State of Massachusetts, have invented a new and useful Improvement in Track Sanding Devices, of which the following is a .full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

My present invention relates to a sand-. ejector which is in the nature of a complete entity in that it is so constructed that the op-@ eration of the simple placing thereof in the sand-box, its attachment to the wall thereof, and its connection at the outer side of the sand-box with the air-supply pipe and with the sand-delivery pipe is all that is required to install it. It preferablyis in the sha'pe'of a structure or case which is adapted to extend through a hole in the wall of the sandbox and to be secured to said wall and so that its inner portion shall be contained within the chamber of the sand-box and its outer portion shall be on the outside of the wall of the sand-box in an accessible position. It is constructed to provide at its inner end Within the sand-box a sand-inlet and at its outer end a sand-outlet,with which the sand-inlet is connected by means of a passage. It also contains an airsupply passage which at its inner end cooperates with the sand-inlet and at its outer end is contained in a section of the structure or case adapted to be connected with an air-supply pipe.

In the drawings, Figure l is a view of iny improved device in side elevation, also showing in vertical section a portion of the wall of the sand-box. Fig. 2 is a view in horizontal section of the device and a portion of the sandbox wall. upon the dotted line 3 3 of Fig. 2. Fig. 4: is a view in vertical Section upon the dotted line 4 4 of Fig. 2. Figs. 5, 6, and 7 illustrate modified constructions of the invention, to which reference is hereinafter made.

Referring to the drawings, A represents a portion of-the wall of a sand-box inwhich is formed upon its side and near its bottom a hole afor the reception ofthe track-sanding device or ejector B,of which one only is shown. It will be understood, however, that usually Y sand-delivery pipe 0 pieces. it in two partsnamely, the part 0 and the v v part 0. Fig. 3 is a view in vertical section the sand-box will have one on each side and "sometimes t'woon each side, according to the requirements of the locomotive.

The track-sanding device or ejector coinprises a hollow shell or case 0, preferably cylindrical in shape and preferably having means for its attachment to the wall of the sand-box, in which is the longitudinal pas- Sage 0', extending from the sand-inlet c at its inner end to its outlet 0 at its'outer end, where it connects with the passage 0 of the The sand-inlet 0 may be of any desiredshape. It is represented in the drawings as provided by the removal of sections of the sides of the shell or case at its inner end to secure the side openings 0 c to the sand-inlet. The sections 0 c of the shell or case and the unperforated end serve as a partialcover, hood, or protection for the inproviding the air-supply passage.

, D is the air-passage, extending lengthwise the case or shell from or near its outer end to or near its inner end, where it is curved ner end'of the pipeor part of the shell or case backward at d that its outlet (1 may face the sand-inlet c and that air delivered through the passage may be forced from its outlet through the sand-inlet and sand-passage 0 into the Sand-delivery pipe. This passage D, I preferably arrange within the shell or case 0. It may be provided by means of an independent pipe (1 as represented at Fig.2,

suitably attached to the case or shell, or it maybe formed in the shell itself, or it may be provided-by an independent pipe parallel With the shell.

The shell or case may be in one or more In the drawings I have represented The latter is in the nature of a coupling. It is attached to the part 0 by the cou'plingnut E, which screws upon the exte pic 6 having the passage 6 screws, the said nipple serving to deflect the air-passage to a right angle and afford means for coupling to the case or shell, by means of the couplingnut 6 the end 0 of the air-supply pipe 6 connecting a source of air-supply (which may be the train-brake system) with the air-passage D. The section 0 also has the interior screw-thread c for use in coupling the end of the sand-delivery pipe C thereto.

The track-sanding device is also represented as having a shoulder F, which forms an abutment upon the inner side of the sandbox wall, and a locking-nut f, adapted to screw upon the threaded section 6 against the outer surface of the sand-box wall and against the shoulder F. Suitable packing may be interposed between the shoulder and the nut, if desired. 'hen this form of the invention is employed, the device is attached to the sand-box wall in the following way: The coupling-section C is removed from the section 0 and also the locking-nutf. The section 0 is then located in the hole a of the sand-box wall, with its inner portion in the chamber of the sand-box and its outer portion outside the wall. The nut f is then screwed home to clamp the case or shell to the wall and the coupling-section C then attached to the section 0 and to the sanddistributing and air-supply pipes.

The section 0 of the case or shell may be placed from the inside of the sand-box or from the outside. I prefer the latter construction, and in Fig. 5 I have represented a form of construction for accomplishing this purpose. The hole a in the sand-box wall is enlarged and threaded. Into this is screwed the sleeve G, having a flange g. The sleeve has the exterior thread g, which engages the thread about the hole and also takes a clamping-nut and the interior thread 1 The interiorlythreaded hole 9 is of a size sufficieut to permit of the passage of the inner end of the case or shell, the case or shell being provided with a threaded enlargement which screws into the threaded hole 9 This construct-ion permits the parts 0 C to be made integral and the whole case or shell to be used as a coupling in uniting the sand-distributing pipe to the sand-box wall and so as to leave the nipple e in proper position to attach to the end of the air-supply pipe. In said figure I have also shown the air supply passage as formed by casting.

In Figs. 6 and 7 I have shown a modification in construction in which the air-supply pipe, instead of passing from one end to the other of the shell or case within it, is arranged upon the out-side thereof and is supported in whole or in part by the sleeve G or the sand-box wall. This variation is shown in order that the scope of my invention may be better understood, as I consider that it includes any construction in which the sanding device is applied to the wall of the sand-box without requiring internal fitting and connection of the parts thereof within the sand-box and in which the connections with the sand-distributing pipe and the air-supply pipe are made with the sand-ejector outside the sand-box and in which the ejector is attachable and removable as a whole from the sand-box by simply inserting a portion of it into the chamber of the box through a hole therein and uniting it to the box or a support by a clamping device or by screwing.

Any medium other than compressed air for forcing or feeding the sand in a manner similar to that in which it is fed by compressed air may be used. Y

I would say that the guard a may have any desired size with respect to the sand opening andinlet. I prefer that it be lar e enough to prevent sand from flowing by gravity into the sand-inlet and through the ejector-passage.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1.
